Heron Lake Plateau So there's this puzzle I work on endlessly

The pack was made up of Redhawks and Blackthorns, so if it wasn't one of his siblings but not one of the Blackthorns then that meant... The cogs in his mind were working a little too fast, but he didn't conclude anything immediately. Screech wasn't sure of who else was left if he excluded those groups, and he found himself recounting and recounting, staring off in to the space above her head as he did so; Redhawk, Blackthorn, Redhawk, Blackthorn, Colt? No, that's a Redhawk. Elwood? Gross, that's beyond silver fox territory — Quixote? His one eye opened as he pinpointed that one not-Hawk, not-Thorn, and then looked at Niamh with an oh my god expression.
